The left channel on my HK AVR 8000 seems to have bit the bullet, being about 6-7 db lower then all other channels. This was one of my original HT purchases, and I way overspent for a receiver. The best part about this old beast is its true amp section, capable of handling 4 ohm loads easily. I need this capability, but I'm wondering if I can get it for what I'm trying to spend ($600)? This is what I'm looking at

Harman Kardon AVR 3600
Onkyo TX-NR709
Marantz SR6005
Yamaha RX-A1000

The Onkyo and Yamaha clearly show 4ohm for front speakers on the back panel, I need this for my LCR. I'm a little nervous about Onkyo, there seems to be some QC issues. I'm leaning toward the Yamaha, but I'm hoping some of you guys can comment that have actually used these various receivers.

Speakers are DIY with a steady 4 ohm load.

Which speakers do you have? Some 4ohm rated speakers are easy to drive and some are very hard for a 'normal' AVR.

The Onkyo SR875 is still around and being sold refurbished. It probably has as much muscle as your HK. The Onkyo NR709 is 4ohm rated but when it is set to 4ohm simply reduces the available power. You might consider something like the Marantz 5005 and run a two or three channel amp for your front speakers.

With your power requirements you won't find too many new AVRs that are going to drive 4ohm speakers very well if they are power hungry. That SR875 is quite the beast.

When all else fails - RTFM!

That's kind of what I was expecting to hear... The speakers are a custom design. The impedence load is fairly linear, between 4-5 ohms over the entire range, except about 4khz where it drops to about 3 ohm. It's also a 93db 2.83V speaker. All in all thats' easy for a 4 ohm capable amp.

I wont be making a purchase till next month, hopefully that SR875 is still around...

I think I might just pick up a Behringer a500 to drive my mains, and then whenever I get a new receiver it will only have to handle a 4ohm center.

Thats a great idea. Since you'll only need an AVR that has preamp outs but not a robust amp section you can lower the budget and still have a decent setup. Get the A500 here.

HK 3600 is the lowest model with preamp outs in the HK line.

Marantz 500x and up all have preamp out jacks. With Denon you'll need to step up to the 33xx level. Onkyo - 70x. The Onkyo 709 (refurbished) is the least expensive AVR that has Audyssey Mult EQ XT. It works very well to correct for in-room reflections and eq's the sub. And it has networking.

When all else fails - RTFM!

It doesn't have preamp out jacks other than for a sub.
